Stainless Steel

LOKRING’s stainless steel fittings are qualified to the requirements of the ANSI/ASME B31 pressure piping codes for pressure and fatigue design, and materials of construction. Extensive mechanical and environmental testing has demonstrated the sealing integrity of the LOKRING connection in a wide range of applications. LOKRING fittings are typically used where fire-safe conditions must be maintained.

NO WELDS, NO FLANGES

NO THREADS, NO LEAKS!

By eliminating welding, many overhead costs relating to safety, personnel, equipment and supplies, inspection, rework, and monitoring can be eliminated or substantially reduced.

Some examples are:

Obtain fire permit for hot work

Erect scaffolding and provide ventilation

“Sniff” area, gas free, and weather protect

Blank flanges and nozzles

Establish fire watch

Build fire box or tarps

Drain, flush, and dry lines

Cranes, welders, grinders, and small tools

Weld consumables (purge gas and filler rod)

Workers’ compensation, insurance, and benefits

Weld X-ray or other NDT

Rework of damaged or misaligned spools

System soak, flush, or passivation; HAZMAT disposal

Maintain and monitor flanges for leakage

In addition, scarce ASME-certified welders are freed up for large bore pipe or pressure vessel welding.
